SPLICEJQINT.

.To all 207mm it may concern:

Be it known that I, PHILIP FOUKES, a citizen of the United States, residing at Pittsburgh,'in the county of Allegheny and State of Pennsylvenia, have invented certain new and useful improvements in Splice- Joints, of which the following is a specificaa joint of novel construction having improved means whereby the necessity of punching holes in the legs of'the derrick to connect the bracing members is avoided end overcome, thereby enabling the cross sectional area: and weight per lineal foot of the legs or uprights of the structure to be reduced the structure to be'feciliteted.

A still further object of the invention is the provision of a splice joint for derricks end similar framedstructures having the novel combinations and, arrangement of parts shown in the accompanying drawings, specifically pointed out in the appended claims and more fully described hereinafter. Referring now, to the drawings, forming part of this specification, Figure tie a side elevation showing part of one len- 01' upright of e derrick, tower, or similzir structure having :3. splice joint constructed and arranged and applied thereto in accordsnce with my invention.

fen-ed construction of the tongues I ing the angle plates. on the derrick legs or. uprights.

In the accompanying drawings, the 1111- moral 2 designates one leg or upright of e derrick or tower which es shown is formed of a rolled metal shape known as 'enengle.

Secured. in holding engagement with the outer surface of 2 is an angle plate 3 which may be formed. by bendinge rolled metal plate, as Shown, but which also may he formed of a piece of rolled metal angleclamped and frictionelly held in position on the leg 2 b y means of clips t, 4, which are similar in construction, these clips having a, rahbet or groove 5 in one edge thereof which is formed to lit and tightly ngage with the rounded edges of the sides oi the angle formingthe leg 2 of the structure. The clips 4: and the angle plate. 3 here registering holes therein through which clamping bolts 6 are inserted, these bolts having asquere shoulder 7 adjacent to the head 8 thereof, so as to prevent turning of the bolt in the holes in tightening the nuts 9 on the bolts to fasten the parts together.

Also secured to the angle plate by means of the bolts 6 for the clips i, tire the girts 10 and 11. and diagonals 12, 13, end 1 15, !forming the bracing, which are conveniently formed of rolled metal angles in theme-liner shown. The openings or holes 16 in the endsforming the square shoulder 7 on thehead end of thebolts 6, 1n this way avoiding the for locat I two sides of the angle The angle plate 3 is necessity of having more than. one set of holes in each side of the angle plat-e 8 in- :fastening the bracing members and the clips 4 to the angle plate 3 end in clamping the angle plate in position on the derrick leg 2. In order to quickly position the engle plate on thederrick leg an integral tongue 17 formedon each leg by slitting the leg as is shown in: Figs. 1 and 6, the so-formed tongue being sprung outwardly so as to form a support on which the lower edge of the angle plate 3 rests in determining the positionof the angle plate lengthwise of the derrick leg 2.

' In assembling the parts to form at derrick. with the splice joints made in accordance with my invention, the angles 2 forming the legs of the structure ere provided with ice . in. the desired position.

the tongues 17 in the shop, but as will be seen by reference to the drawings, no through holes need be punched in the derrick leg to attach the bracing members, so that the strength and stiffness necessary is secured with the use of an angle of much lighter Weight than is required when a series of holes are punched in the sides of the angle to fasten the parts together.

The bent plate or angle plate 3 is then secured to the leg 2 in the desired position by means of the clips 4 and bolts 6, and when positioning the angle plates 3 on the leg 2, the girts and diagonals are also fastened thereto by the bolts 6 l The rectangular holes 16 in the girts and diagonals are elongated so to provide for adjustment in squaring up the structure. After this; is done the nuts 9 on the bolts are turned on the bolts so as'to tightly clamp the clips l and angle plate 3 on the derrick leg 2 and frictionally hold the angle plate is at the same time are fastened to the the bracing members and rigid structure angle plate, a strong is obtained.

The advantages 0% my invention, which will be appreciated by those skilled in the art, arise from tie novel manner of connecting the di gonal members and girts to the legs of M18 structure, and by the omission of throi gh holes in the legs of the structure, By ayoiding the use of holes in the legs of the structure the cost or fabrieating is reduced, While the Weight of the structure is .materally lessened Without sacrifice in strength stillness.

Modifications in the details or" the constriiction of the splice joint, and the nuanner of fastening the bracing members thereto, may be made Without departing from my invention as defined in the appended claims.

I claim 1. A splice joint for derricks and similar structures comprising an angle plate engag ing the sides of the derrick'leg, plate being adapted to connect the members of the leg bracing, clips engaging the edges or" said leg to clamp the angle plate in position thereon, said bracing clips and angle plate having registering bolts in said registering holes for securing the clips to the angle plate and thereby 4 derrick leg bracing said angle holes therein and assesses clamping the angle plate on the derrick leg and fastening the bracing to the an le plate.

2. A splice joint for derricks and similar structures comprising an angle plate to engagejthe sides of the to the angle plate and engaging the edges of the derrick leg to thereby clamp and frictionally hold the angle plate in position on the derrick leg, said angle plate having the fastened thereto, and said bracing, angle plate, and clips having registering holes therein, and bolts extending through said registering holes.

3. A splice joint for derricks and similar structures comprising an. angle plate to on. gage the sides of the derrick leg, clips bolted to the angle plate and engaging the edges of the derrick leg to thereby clamp and trictionally hold the angle plate in position on the derrick leg, said angle plate havingthe derrick. leg bracing fastened thereto, and means formed on the derrick leg to engage with and fix the position of the angle plate lengthwise on the l. in a derrick or s'niilar structure the combination of a of the derrick, diagonal braces and girts formed oi filled metal shapes, and, a splice joint for i: ening the diagonal braces and girts to the l said splice joint having z: gaging the sides and clips e edges of said leg, with re ate: the angle plate and clips, the ends of vthe diagonal bra and bolts eZ-Ztendlng through holes-oi": the bracing and regist :71 b in the clips and angle plate, to clamp the parts in assembled relation.

5. In a derrick or similar structure the combination of a-derrick leg, girts 1d diagonal b aces, and a splice joint fastening the girts and braces to the derrick said splice joint having an angle plate and clips frictionally engaging the derrick leg, With registering hole in the angle plate and clips, and slotted i in the ends of the girts and braces, and soils extending throng; .id holes, to cl the angle plate on the derick leg and fasten. the girts and braces to the angle plates.
